            Bug ID: 14561
           Summary: OpenJDK does not compile when building in WSL
           Product: buildroot
           Version: 2021.11
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: colin.foster@in-advantage.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

Tested in 2021.11. As the summary suggests, when building in WSLv2, OpenJDK
fails. If I were to wager a guess, OpenJDK is trying to be too smart about the
fact that it is building on a Windows OS. Jumping to a Linux machine and
compiling with the same config works as expected.
